Residential Water Pollution

Keep It Clean Downstream
Excess irrigation and wash water contributes to pollution at local beaches. This water can carry excessive fertilizer, pesticide, herbicide, automobile fluid, paint, trash, animal waste, and other pollutants to the storm drain system that flows untreated into channels, harbors, and the ocean where it can endanger marine life and contaminate beaches.

Causes

Common Household Cleaners

Detergents From Washing Your Car

Fertilizers

Improper Disposal Of Paint, Oil, or Other Chemicals

Insecticides, and Fungicides

Loose Grass Clippings and Leaves

Pet Droppings

Poorly Maintained Septic Systems

Soil From Exposed Areas in the Yard

Weed Killer

Effects

Soil in runoff carries contaminants that smothers and kills aquatic life.

Fertilizers, car exhaust, and detergents cause explosive plant and algae growth, which depletes water of oxygen, killing fish and animals as well as creating a terrible smell.

Loose grass clippings and leaves also add to this and clog drainage systems.

Pet droppings and septic tank overflows can cause diseases like dysentery, hepatitis, and parasite infections by getting into drinking water and recreation areas.

Oil, paint, cleaning supplies, and other toxic materials from cars and batteries contaminate drinking water and kill fish, animals, and plants.

Solutions

Adjust sprinklers to minimize water from entering the gutter. When possible, use drip irrigation. This will also reduce water usage.

Don’t use the hose to clean walkways, driveways, or gutters. Whenever possible, use a rake or broom to clean the yard, driveway and gutters. Use leaf blowers responsibly and never blow debris into the gutter or storm drain.

Pick up pet waste and place in the trash. Never wash pet waste out into the street or into the storm drain.

Wash vehicles at car washes that have water reclamation systems.

Promptly fix all vehicles that leak fluids.

Place absorbent material such as cat litter on any drips to clean up spills and dispose the material in trash.
